You're attributing views to me I do not hold.

And frankly, you characterization of those views makes clear you're not interested in actual answers.

The primary issue with gentrification in historically black neighborhoods is that owners face the dilemma of having to leave their community to capture the increased property values.

For example, I live near the oldest black church in the PNW. Many of the older congregation members live in the area, and have low mobility. If we don't build a mix of housing that addresses their needs in downsizing, they end up having to effectively exile themselves from the community they've lived within for decades. They can't simply "move somewhere lower cost" without dramatic changes to their entire social world, just at an age where keeping those social ties takes a lot of effort.
